Haskell strict concurrency abstractions; profiling libraries

This package provides head normal form strict versions of some standard
Haskell concurrency abstractions (MVars,Chans), which provide control
over where evaluation takes place not offered by the default lazy types.
This may be useful for deciding when and where evaluation occurs,
leading to improved time or space use, depending on the circumstances.

This package provides a library for the Haskell programming language, compiled
for profiling. See http://www.haskell.org/ for more information on Haskell.
